National Immigration Law Center guide
Revised date
The National Immigration Law Center (NILC) publishes the "Guide to Immigrant Eligibility". This Guide contains descriptions and pictures of key citizenship and immigration documents and information on how to decipher the coding on these documents.
The NILC Guide is maintained by the National Immigration Law Center and may not contain a complete list of immigrant statuses and documents. If you encounter an individual with a status or document that is not on these lists, or an individual claims legal status but has no supporting documentation, please contact HCA Area Representative.
